I assume it is the markup language.
If I try to put a digit in a comment, and it's the first thing on the line, it gets changed. For instance,
- I entered this line with a four at the start.
Also happens for quotes:
- I entered this line with a four at the start.
In both cases, the "4." I entered at the start of the line is changed to a "1." The "1." shows up on preview, and shows up when I submit.
This makes it rather difficult to quote a single term from the T&Cs of a deal. Looks like a bug to me.
Numbered lists are automatically numbered. To override, put a backslash inbetween the number and the dot.
